I'm looking to upgrade my brakes (Stoptechs). I notice some folks upgrade only the front and some folks upgrade both.

Considering long-term reliability of the car's overall braking & suspension system.

Is it better to upgrade the front and rears? Also, do all cross drilled rotors develop cracks over time?

***I don't plan to drift or autocross, but may drive it hard at times and may eventually add a HKS SC with cams in the future***.
As you may know these upgrades are costly, and I want to do it right the first time. Thanks in advance for feedback.!

 

Some people just upgrade the front for now & purchase the rears later because the front is where most of the hard breaking will effect. Also, it is a more cost effective way of approaching it when you don't have the cash to spend on a complete kit which is roughly 4-5K since you're considering StopTechs. As far as what kind of rotors, it really dosn't matter for you especially since you don't track your car. Even with occasional track time you really wouldn't notice the difference in perormance (drill, slotted, drill/slotted). I'd say go with what looks better in your case. What will matter is the quality of your pads.
